Automatic movement of a watch: How does it work?

Automatic watch movement

Moving an automatic watch, how does it work?

Charlie Paris lights you on automatic reassembled mechanical motion through its watches Made in France


The movement of a watchis the mechanism that allows a watch to work. At Charlie Paris, we provide ourselves with different manufactures in order to create man watches and woman watches quality: Citizen, a Japanese manufacture for automatic movements; and Ronda, a Swiss manufacture for our watches in QuartzThe Swiss watch brands generally own their own manufacture, which is why their prices are very high. 

For our watches, we use two large families of movement :
  • Watch movements in Quartzwhich are simple mechanisms and that work with a stack. These movements have the advantage of being the most accurate.
  • Themovements of mechanical watch, use wheels and springs to operate with kinetic energy. That is, the energy a body has from his movement. The latter are more complex to manufacture and design, and are the chouchous of watch enthusiasts and collectors.They prove real know-how. Ours man automatic watches, and our woman automatic watches are all endowed with the Japanese Citizen movement.

To understand the operation of an automatic watch movement, you have to learn more about its main components!

The main components are:
- Therotor: c’est la masse oscillante du mécanisme. In clear, it is a half-circle weight attached to motion. It rotates at 360° depending on the wrist movements and allows, through a series of mechanisms, to re-assemble the barrel spring thus providing mechanical energy to the watch.
- Lacrown: It is the small wheel on the right side of your watch. It is attached to the remontoir tree and is used to remount the engine spring.
- Thebarillet spring: It is an elastic steel band that provides the energy needed for movement when armed, i.e. tense.
- Thetransmission system(red): It transmits the energy accumulated in the barrel spring to the exhaust wheel via a series of small wheels.
 - The exhaust wheel: it is the function of allowing the energy carried by the wheels to be escaped to the anchor, intermittently and regularly. It is the watch maintenance body.
- Thebalancier: It is the heart of movement. It beats between 5 and 10 times per second in a circular manner. He is the originator of the “tic-tac”, a noise produced by pallets on the teeth of the exhaust wheel, due to its movement of the way forward. It is the regulator of the movement.
- Theruby: These are stones of great hardness that reduce the friction and wear of the components of the mechanism.

3 - The operation of an automatic watch movement

Now that you know perfectly the main components of the mechanical motion, how does an automatic movement actually work?

The following are the six main steps that help you understand more about how your watch needles rotate:

     1. The movements of the wrist spin the rotor and thus go back toe barrel spring. The reassembly can also be done by turning the crown;
     2. The transmission system transfer energy to lan exhaust wheel;
     3. Exhaust doses energy in regular sections;
     4. The balancier Use this regular energy to beat in a constant way;
     5. Each battement series, a series of wheels transfer energy to needles watch;
     6. The needles move on the dial.

Our automatic movement watches include a swinger that recharges the barrel spring by wrist movements. Thus, if the watch is worn regularly, there will be no need to manually pull it up.

Automatic watcheshave a beautiful aesthetic advantage. The second needle does not take a leap of a second but much more small jumps. The whole thing is more linear.
